A method of manufacturing support elements for lighting devices includes: providing an elongated, electrically non-conductive substrate with opposed surfaces, with an electrically-conductive layer extending along one of said opposed surfaces, etching said electrically-conductive layer to provide a set of electrically-conductive tracks extending along the non-conductive substrate with at least one portion of the non-conductive substrate left free by the set of electrically-conductive tracks, forming a network of electrically-conductive lines coupleable with at least one light radiation source at said portion of said non-conductive substrate left free by the electrically-conductive tracks. Said forming operation includes selectively removing e.g. via laser etching a further electrically-conductive layer provided on said non-conductive substrate, or printing electrically-conductive material onto the non-conductive substrate. The electrically-conductive tracks and the network of electrically-conductive lines may be coupled with each other e.g. by means of electrically-conductive vias extending through the non-conductive substrate.

Method of manufacturing support structures for lighting devices and corresponding device

According to the present disclosure, a support structure for lighting devices, e.g. LED lighting devices, is provided with an electrically insulating core layer having a first and a second mutually opposed surfaces, with mounting locations for electrically-powered light radiation sources on the first surface, a network of electrically conductive lines printed on said first surface, at least some of said electrically conductive lines extending between the mounting locations and fixed locations on the first surface, and electrical distribution lines of electrically conductive material on the second surface of the core layer, and electrically conductive vias extending through core layer and electrically coupling the electrical distribution lines on the second surface with the electrically conductive lines at said fixed locations on the first surface.
